🔪 How To Make Crispy Roasted Sweet Potatoes
Step One: Peel your sweet potato and dice into 1-inch cubes. This size is perfect for even roasting, giving you that crispy outside and tender inside.
Step Two: In a large bowl, mix the cubed sweet potatoes with melted butter, salt, pepper, and brown sugar. Give everything a good stir so each piece is nicely coated in that buttery, sweet goodness.
Step Three: Lay the sweet potatoes out in an even layer on a baking sheet. Pop them in the oven at 400 degrees and let them roast for 20 minutes to start crisping up.
Step Four: Take the sweet potatoes out of the oven, give them a little stir, and sprinkle the chopped bacon on top. Put the tray back in the oven for another 10 minutes to let everything get golden and crispy. Serve warm and enjoy every savory, sweet bite!
👩🍳 Expert Tips
To get perfectly crispy roasted sweet potatoes, try these simple tips:
- Use High Heat: Roast at 400°F or higher to help the potatoes caramelize and develop a nice crispy texture.
- Dry the Potatoes Well: After peeling and cutting, pat the sweet potatoes dry to remove any excess moisture—this helps them crisp up.
- Flip Halfway Through: Stir or flip the potatoes about halfway through cooking to brown them evenly on all sides.
💭 FAQs
Yep, sweet potato and kumara are pretty much the same thing! “Kumara” is what we call it here in New Zealand, while “sweet potato” is the name most people in the U.S. use. There are a few different varieties out there, but they all bring that tasty sweetness and gorgeous color we love. So go ahead and use them interchangeably—no matter what you call it, it’s going to be delicious!
No. There’s no need to parboil sweet potatoes before roasting! Sweet potatoes cook up beautifully and get perfectly crispy just by roasting them directly. Skipping the parboiling step saves time and still gives you that caramelized, tender goodness we all love!
Not exactly! Purple sweet potatoes are denser than regular sweet potatoes, so they often need a bit more time to roast. You might need to add an extra 5-10 minutes to ensure they’re tender all the way through. Just keep an eye on them and check for doneness with a fork.
To make these in the air fryer, cook the seasoned sweet potato cubes at 400°F for 15-20 minutes, shaking halfway through for even crispiness.
It’s best not to add baking soda to your sweet potato cubes. Baking soda can break down the surface too much, making them mushy instead of crispy. Just stick with oil and seasonings for the perfect roasted texture!
The best way to store sweet potato cubes is to keep them in an airtight container in the fridge. If they’re already cooked, they’ll stay fresh for up to 4 days. For raw cubes, store them submerged in water to prevent browning, and use within 2-3 days for the best texture. Just make sure to drain and pat dry before cooking!
No, you don’t have to use bacon! These crispy roasted sweet potatoes are tasty on their own, but you can skip the bacon if you prefer a plain roasted sweet potatoes recipe. They’ll still turn out delicious and flavorful!
For this recipe, roast your cubed sweet potatoes in the oven for 30 minutes to get them perfectly crispy and tender. If roasting purple sweet potato, keep in mind they may need a bit more time, as they tend to be denser—just check for doneness and adjust as needed!
